Designing an efficient reverser system

Hi Guys,

I've been scratching my head for a while trying to design myself throttle levers which also account for the reverser segment. I'm hoping to build a 727 system, and I dont have any original components. I'm open to using a pulley wheel/ gear combination or just a gear system to connect with the pots for the input.

Is there any easy way to design a throttle lever encompassing the reversers? The easier it can be designed in CAD the better as I've ordered a 3D printer for myself to help build the majority of my components.

Thanks guys,

James.
